हिन्दीDetermine the maximum acceleration of a train in which a box lying on its floor will remain stationary, given that the coefficient of static friction between the box and the train's floor is \( 0.15 \). (Take \( g = 10\text{ m s}^{-2} \))
Correct answer · Option 1
\( 1.5\text{ m s}^{-2} \)
Explanation
Acceleration of box is provided by static friction: \( m a \le f_{s,\text{max}} = \mu_s m g \implies a_{\text{max}} = \mu_s g = 0.15 \times 10 = 1.5\text{ m s}^{-2} \).
